10. Compare the wattmeter reading with the RF power output range of 15 watts or less. This limit exists
because the multi-band (untuned) antenna has a VSWR of 3:1.
Transmit only for as long as needed to take the measurement, then immediately disable
the transmission.
11. If the wattmeter reading is within the range, record the value in the appropriate space on the data
collection form near the end of this manual.
If the wattmeter reading is outside the range, make sure the antenna is consistent with the specified
frequency range of the radio. Recheck all antenna connections, and measure the reverse power again.
If these checks/corrections fail to produce a reading within the range, replace the antenna and repeat
the entire antenna test procedure. Any value exceeding the maximum allowable reflected power value
will result in a diminished RF output signal. If problems persist, contact the Technical Assistance
Center (see page 21).
12. Repeat on test channels within the other RF bands, until at least one channel in all bands has been
tested.
13. Disconnect the coaxial cable jumper and wattmeter.
14. Permanently connect the cable from the vehicle-mounted antenna to the radio’s antenna cable by
mating the two TNC connectors together. Use two pairs of soft-jaw pliers to gently tighten this
connection. Do not over tighten and do not twist either cable.
15. Make several test calls on the radio system to verify operation of the mobile radio. Before making the
calls, select other talk groups or conventional channels, as required to verify operation.
To prevent RF leakage and ensure peak performance, make sure the RF connectors are
tight, but do not over-tighten so connector damage will not occur.
Improper installation of the RF cables may lead not only to poor radio
performance but also to harmful exposure to RF electromagnetic energy.
Testing is complete. The radio is now ready for normal communications.
